Effect of SlMYC1 Downregulation on Volatile Terpene Levels in Stem and Leaf Trichomes of Tomato.

Levels of volatile terpenes in (A) stem and (B) leaf trichomes from wild-type (WT) and ir-SlMYC1 line 8, 18, and 25 plants, as quantified by gas chromatography-mass spectrometry (GC-MS). The terpene levels in stem trichomes were normalized by stem surface area and in leaf trichomes by leaf fresh weight. Bars represent the mean values (±se) of three to four biological replicates, each consisting of multiple stem pieces or leaflets from different plants. Bars annotated with different letters were significantly different according to Fisher’s LSD test (P ≤ 0.05) after ANOVA.
